CX-Ray is Sapim's most versatile aero spoke. Sapim claims the CX-Ray has the highest fatigue test values of any spoke available. Its unique strength and flexibility make the CX-Ray suitable for most high-end bicycle disciplines from road racing to Triathlon and even Downhill. The CX-Ray fits all standard hub holes due to it's 2.3mm maximum dimension at the widest portion of the blade. With a weight nearly 30% lighter than standard double butted spokes, it is almost as light as Titanium. CX-Ray aero spokes are produced from high-tensile, fatigue-resistant 18/8 stainless steel, ideally suited for the rigorous demands of cycling.

Sapim's CX-Sprint offers many of the same benefits are the more expensive CX-Ray: an aerodynamic, bladed profile, unparalleled, tensile strength and fatigue life, and light weight. While a little heavier (about a gram) than the CX-Ray, the additional mass brings greater strength, stiffness, and durability, making this an ideal spoke for heavier riders or just a little added stiffness on the drive-side.
